How does it cause vision loss?

The Effects of Glaucoma

Elevated IOP

Abnormally high IOP is caused by a buildup of a fluid (aqueous humor) within the eye. This fluid normally drains through the front of the eye where the iris and cornea meet. When fluid is overproduced, or there is a problem with drainage, IOP can reach dangerous levels.

Damage to the Optic Nerve

Increased IOP can cause small fibers in the optic nerve to stop functioning properly. As this nerve begins to deteriorate, your vision can become permanently compromised.

How can I protect my vision?

"It appears that OPP (ocular perfusion pressure) is largely determined by cardiovascular fitness. We cannot comment on the cause, but there is certainly an association between a sedentary lifestyle and factors which increase glaucoma risk."

It is very important to undergo regular eye exams every two years, or once per year if you are age 60 or older.

A tonometer is used to measure your IOP.

There are 3 primary steps:

Your eye is typically numbed with eye drops.

A small probe gently rests against the surface of the eye.

Other tonometers send a puff of air onto the surface of the eye.

A short, painless exam can reveal glaucoma symptoms and help protect your vision.

What are my treatment options?

Four Primary Glaucoma Treatments

Eye Drops

Some medicated eye drops can reduce the amount of fluid that is produced by the eye, while others can improve drainage.

Medications

Your doctor may recommend a beta blocker or similar medication that can decrease the amount of fluid that is produced in the eye.

Laser Surgery

Your doctor may use a laser to open the drainage canal and improve the outflow of fluid.

Medical Marijuana

While the American Academy of Ophthalmology maintains their position that medication and surgical treatments have been tested and proven as effective for glaucoma, several studies have also shown that medical marijuana may temporarily lower intraocular pressure in patients. Having an open and honest conversation with your doctor can help you choose the right treatment for you.

Glaucoma typically presents without symptoms, and can quickly lead to loss of vision or total blindness without the appropriate treatment.
